Critical Blockers + +These **must** be resolved before any production or PyPI release. + +### 1.1 — 623 mypy Errors Under Configured Strict Mode + +**Location:** `pyproject.toml` line 58 configures `[tool.mypy] strict = true`, but +running `mypy spinstep/` produces **623 errors** in 5 of the 9 checked source files. + +**Root causes:** + +| Cause | Affected Files | Example | +|-------|---------------|---------| +| Missing `scipy` type stubs | `traversal.py`, `discrete.py`, `discrete_iterator.py`, `quaternion_utils.py` | `Library stubs not installed for "scipy.spatial.transform"` | +| Missing `sklearn` stubs | `discrete.py` | `module is installed, but missing library stubs or py.typed marker` | +| `ArrayLike` too broad for indexing/unpacking | `quaternion_utils.py` | `Unsupported operand type for unary -` on `ArrayLike` parameter | +| `Any` return types from dynamic calls | `discrete.py`, `quaternion_utils.py` | `Returning Any from function declared to return "ndarray"` | +| `object` attribute access | `quaternion_utils.py:103-104` | `"object" has no attribute "orientation"` | + +**Impact:** Downstream users who enable mypy will see errors when type-checking +code that uses SpinStep. The project's own CI does not run mypy, masking these. + +**Suggested fix:** + +1. Install `scipy-stubs` in dev dependencies. +2. Narrow `ArrayLike` parameters to `np.ndarray` or `Sequence[float]` where + appropriate. +3. Define a `Protocol` for node-like objects (`get_relative_spin`, + `get_unique_relative_spins`) instead of `object`. +4. Add `mypy spinstep/` as a CI step (can start with `--ignore-missing-imports` + and progressively tighten). + +--- + +### 1.2 — No PEP 561 `py.typed` Marker + +**Location:** `spinstep/py.typed` does not exist. + +**Impact:** Even after fixing the mypy errors, downstream projects that `pip install +spinstep` will not receive type information because pip and mypy use this marker to +detect typed packages ([PEP 561](https://peps.python.org/pep-0561/)). + +**Suggested fix:** + +1. Create an empty file `spinstep/py.typed`. +2. Ensure it is included in `MANIFEST.in` and in the wheel (verify with + `unzip -l dist/*.whl`). + +--- + +### 1.3 — STATUS.md Contains Stale Information + +**Location:** `STATUS.md` + +**Details:** The file states: + +> *"CI workflow content is stored in `.github/workflows_disabled`… No active +> GitHub Actions workflows exist in `.github/workflows/`."* + +This is **no longer true**. The CI workflow is now active at +`.github/workflows/ci.yml` and recent runs on `main` pass. New contributors +reading STATUS.md will be misled. + +**Suggested fix:** Update STATUS.md to reflect the current CI state, test counts +(51 collected, 46 passed, 5 skipped), and remove references to the disabled +workflow. + +--- + +## 2. High-Priority Issues + +These should be addressed before a production release but are less severe than +the critical blockers. + +### 2.1 — Incomplete `project.urls` Metadata + +**Location:** `pyproject.toml` lines 44-45 + +**Current state:** Only `Repository` is listed. + +**Missing:** +- `Homepage` +- `Documentation` (could point to `docs/index.md` or a GitHub Pages site) +- `Bug Tracker` (e.g., `https://github.com/VoxleOne/SpinStep/issues`) +- `Changelog` (e.g., `https://github.com/VoxleOne/SpinStep/blob/main/CHANGELOG.md`) + +**Impact:** PyPI renders these as sidebar links. Without them the package looks +incomplete and users cannot easily find issue tracking or docs. + +### 2.2 — No `keywords` for PyPI Discoverability + +**Location:** `pyproject.toml` + +**Suggested addition:** +```toml +keywords = ["quaternion", "traversal", "rotation", "orientation", "3D", "spatial", "tree"] +``` + +### 2.3 — No Code Coverage Reporting + +**Location:** `.github/workflows/ci.yml` + +**Current CI steps:** `ruff check` → `pytest tests/`. No coverage measurement. + +**Impact:** There is no visibility into which code paths are untested. The project +has good coverage in practice (~90% of core paths), but this is not tracked or +enforced. + +**Suggested fix:** +1. Add `pytest-cov` to dev dependencies. +2. Add `--cov=spinstep --cov-report=term-missing` to the pytest invocation. +3. Optionally upload coverage to Codecov or Coveralls. + +### 2.4 — CI Does Not Run mypy + +**Location:** `.github/workflows/ci.yml` + +The CI runs `ruff check` but **not** `mypy`. With 623 errors this step would +fail immediately. Once the mypy errors are fixed, adding it to CI prevents +regressions. + +**Suggested fix:** Add a `mypy spinstep/` step to CI after the ruff step. + +### 2.5 — `CONTRIBUTING.md` References Wrong Linter + +**Location:** `docs/CONTRIBUTING.md` line 24 + +**Current:** `"check with flake8"` + +**Should be:** `"check with ruff"` (matching `pyproject.toml` and CI). + +### 2.6 — Silent Handling of Zero-Norm Quaternions + +**Location:** `discrete.py` lines 47-56 + +**Behavior:** If a mixed array is passed where **some** quaternions are zero-norm +and others are valid, the zero-norm rows silently remain as `[0, 0, 0, 0]` in the +stored orientations. They are only handled later in `query_within_angle` and +`traversal.py` via ad-hoc `np.allclose(…, [0,0,0,0])` checks. + +**Impact:** Users may unknowingly pass partially-invalid data and get unexpected +results. Inconsistent state in the orientation set. + +**Suggested fix (pick one):** +- **Option A (strict):** Raise `ValueError` if *any* quaternion has zero norm. +- **Option B (filter):** Silently drop zero-norm rows and warn via `warnings.warn`. +- **Option C (document):** Add explicit documentation that zero-norm quaternions are + retained as-is. + +### 2.7 — Duplicate / Conflicting Dev Dependency Files + +**Location:** `dev-requirements.txt` vs `pyproject.toml [project.optional-dependencies.dev]` + +Both define dev dependencies but with different content: + +| Source | Contents | +|--------|----------| +| `dev-requirements.txt` | `pytest`, `black`, `ruff`, `mypy` | +| `pyproject.toml [dev]` | `pytest`, `black`, `ruff`, `mypy` | + +Currently they match, but the dual-file pattern invites drift. The +`dev-requirements.txt` file is not referenced anywhere in CI (which uses +`pip install .[dev]`). + +**Suggested fix:** Remove `dev-requirements.txt` to keep a single source of truth, +or generate it from pyproject.toml (`pip-compile`). + +--- + +## 3. Medium-Priority Improvements + +### 3.1 — Missing Test Coverage for Key Paths + +| Area | Status | Details | +|------|--------|---------| +| `get_unique_relative_spins()` | ⚠️ Skipped | Requires `healpy` (not in CI) | +| GPU / CuPy paths | ⚠️ 4 tests skipped | No GPU in CI | +| Batch `query_within_angle(N, 4)` | ❌ Not tested | Only single-quat path tested | +| `from_sphere_grid(n_points=0)` | ❌ Not tested | Edge case: empty grid | +| `DiscreteOrientationSet(None)` | ❌ Not tested | Should raise `ValueError` | +| `rotation_matrix_to_quaternion` edge cases | ❌ Not tested | Only identity + random tested | + +**Suggested fix:** Add targeted tests for the above. For `healpy`, consider adding +it to a CI optional-test job. + +### 3.2 — No Release / Publishing Workflow + +**Current state:** No CI job for building and uploading to PyPI on tag/release. + +**Suggested fix:** Add a workflow that: +1. Triggers on GitHub release creation or tag push. +2. Builds sdist + wheel with `python -m build`. +3. Publishes to PyPI via `twine upload` or the `pypa/gh-action-pypi-publish` action. + +### 3.3 — No `SECURITY.md` at Repository Root + +**Location:** GitHub looks for `SECURITY.md` in the root or `.github/` directory to +display a "Security" tab with vulnerability reporting instructions. The project has +`docs/annex-security.md` but this is not detected by GitHub. + +**Suggested fix:** Create `SECURITY.md` at the root with vulnerability reporting +instructions. + +### 3.4 — No Dependency Scanning / Dependabot + +**Current state:** No `dependabot.yml` or similar tool configured. + +**Impact:** Security vulnerabilities in dependencies (`numpy`, `scipy`, +`scikit-learn`) won't be flagged automatically. + +**Suggested fix:** Add `.github/dependabot.yml` for pip ecosystem. + +### 3.5 — `egg-info` in sdist + +**Location:** The sdist tarball `dist/spinstep-0.1.0.tar.gz` includes +`spinstep.egg-info/` which is a build artifact. + +**Impact:** Minor — adds ~5 unnecessary files to the source distribution. + +**Suggested fix:** This is a setuptools default behavior. Ensure `.gitignore` +excludes `*.egg-info/` (it does) and consider using `hatchling` or `flit` as a +modern build backend that avoids this. + +### 3.6 — README Contains Inaccurate Links and Broken HTML + +| Line | Issue | +|------|-------| +| 1 | Link to `VoxLeone/SpinStep` — the GitHub organization is `VoxleOne` (lowercase `l`) | +| 78 | `` tag has unclosed `style` attribute: `style="max-width: 100% style="margin: 20px;"` — missing closing quote | +| 195 | Clone URL says `VoxLeone/spinstep` — the GitHub organization is `VoxleOne` (lowercase `l`) | + +--- + +## 4. Low-Priority Polish + +### 4.1 — License Header References `LICENSE.txt` + +**Location:** All source file headers say `"See LICENSE.txt for full terms."` but +the actual file is named `LICENSE` (no `.txt` extension). + +### 4.2 — No `__all__` in Utils Subpackage + +**Location:** `spinstep/utils/__init__.py` exports nothing. Individual utility +modules (`quaternion_utils.py`, `quaternion_math.py`, `array_backend.py`) also +lack `__all__` definitions. + +**Impact:** Consumers doing `from spinstep.utils import *` get nothing useful, and +it's unclear which functions are considered public API. + +### 4.3 — No `pre-commit` Configuration + +Adding a `.pre-commit-config.yaml` with `ruff`, `black`, and `mypy` hooks would +prevent style/type regressions from being committed. + +### 4.4 — `batch_quaternion_angle` Uses `Any` Types + +**Location:** `quaternion_math.py:12` + +Parameters `qs1`, `qs2`, and `xp` are all typed as `Any`. This provides no type +safety. Consider using `np.ndarray` for the quaternion arrays and +`types.ModuleType` for `xp`. + +### 4.5 — Factory Methods Missing `cls` Type Annotation + +**Location:** `discrete.py` lines 147, 153, 159, 170 + +The `@classmethod` factory methods (`from_cube`, `from_icosahedron`, +`from_custom`, `from_sphere_grid`) don't annotate the `cls` parameter. + +--- + +## 5.
